Star Trek: The Original Series premieres in Flanders, the Dutch speaking part of Belgium, with the episode "De eindeloze ruimte" ("Where No Man Has Gone Before"). The episode was broadcast on channel BRT 1, in the prime timeslot 18:05-18:55. Unlike the French and German speaking parts of the country, the Flanders episodes were not dubbed, but subtitled and over the course of nearly one year, about half of the series was broadcast.

The second Original Series episode "Noodsignalen" ("Balance of Terror") is broadcast in Flanders on channel BRT 1, in the prime timeslot 17:55-18:45.

30 September - Star Trek: The Original Series premieres in The Netherlands with the episode "Waar geen mens ooit eerder was" ("Where No Man Has Gone Before"). The episode was broadcast on channel Nederland 1, in the timeslot 15:35-16:25. As usual in The Netherlands, the episodes were not dubbed, but subtitled and over the course of nearly one year, about half of the series was broadcast. However, as with Flanders, the episode titles were translated into Dutch in their TV guides. As of 2014, and unlike the later Star Trek films which repeatedly were, this was the only time a Star Trek television series had been broadcast on Dutch television as none of the others ever were. Dutch Belgium would later see a partial broadcasting of Star Trek: The Next Generation. Neither Dutch nor Flanders TV followed the American broadcast or production order, but broadcast episodes from all three seasons in a rather haphazard order. At the time state-owned both nation's channels did not use the commercial break format.

7 October - The second episode of The Original Series episode "The Trouble with Tribbles" is broadcast in The Netherlands. The episode was broadcast on channel Nederland 1, but now moved up to the prime timeslot 19:05-19:55.
